Nvidia Drivers ( proprietary not nouveau ) - Debian 12 - ZBOOK Fury G7

[EliotCole]

Hi, All
 

I've done a fair bit to get where I am using the "non-open source" drivers ... but I can't seem to get around boot errors (not the requested fix) and I don't believe that the system is *really* using the dedicated GPU.
 

So, I know that HP officially ships / supports a Ubuntu distribution, which I am not using, but I was wondering if someone a bit more clever than I am with Debian based systems can help me through getting these running right.
 

Basically, I'd like to be able to use hardware acceleration in applications without the system crashing (that's not the issue that I'm raising, please don't try to fix that) and generally be able to use this Wayland system a bit more optimally than I currently am.
 

Basically, my ask is:

Does anyone know how to get the Proprietary NVidia drivers installed correctly for Debian 12 running Gnome 3 on Wayland?
 

Happy to provide relevant details, but this is a work laptop, so I will obfuscate where necessary.

Spoiler

Additional Information

General

I have been through the Bookworm install, here, on the Debian wiki. I also tried both with and without this backports thingumy, mentioned in this reddit thread. I had also tried with and without running apt purge nvidia-* before doing anything.
 

I can't remember the exact errors on boot, but, again ... I am not *specifically* trying to fix those. I just need a guide to get the proprietary drivers installed on this system.
Still, if you wish to know what they are ... I don't have a clue how to access the logs on this system, as they don't appear in the logs folder ... but to memory, it's just a generic 'something failed' error with red letters. I do seem to remember finding something around nvidia-persistenced.service ... but that could be a red-herring, dunno.
Again, though ... any immediate focus just on this will be ignored ... I am happy to purge and start again.
 

Everything else is up to date in general.
 

If I think of anything more I will either update this prior to any responses, or update this and indicate with a response.

System Information

I'm running a Gnome3 Wayland desktop and that will not be changing.

Hope that it goes without saying that I do not expect, nor feel entitled to, anyone's assistance, here.

[Influential_El]

This was far from easy, but I believe that the main things that got me around the edge (there's still a couple of errors at boot, but hopefully not nvidia related) were to do the following before the Nvidia install:

1. Install Linux Headers
2. Purge Nvidia 'stuff'
3. Add backports

This should get you to the point where you can install without needing to do the dkms stuff in the reddit thread I listed. But if it doesn't work, try that after the above ...

Once you have installed, you're not out of the woods yet, as you need to sign the drivers manually.

Unfortunately I can't remember what guide I used, but none of it is obvious. Plus, if you're fresh in on Debian 12, they're not where any of the guides say ... I think they're in a DKMS folder somewhere, though.

You may also need to ensure some NVidia things load first in grub ... I'm not entirely sure. Sorry. I wasn't taking notes! 😩
